The document discusses the lecture method of teaching. It defines a lecture as a discourse given by a teacher to students on a given subject for instructional purposes. The key purposes of lectures are to stimulate thinking in students, develop concentration, achieve cognitive objectives, and influence learning habits. An effective lecture includes an introduction to engage students, a body to cover content in an organized manner, and a conclusion to summarize main points. Lectures allow for presenting information to many students at once but do not promote individual needs or independent learning.
